The textures are cubemap distortion compensated and can be used in 3D modelling software and game development engines (such as Unity 3D) to create seamless space environments.

Note that some development tools treat skybox textures differently so it may be necessary to rotate images depending on your software. The orientation of images are compatible with Unity 3D and for 3DS Max the 'Up' and 'Down' images should be rotated by 180 degrees.
